. Figure 199.—Maxillary protuberances of Uintatherium segne, Marsh (NTo. 1194); seeu from above. FiGUEE 200.—Tlie same specimen; seen from in front. m'. maxillary protuberance; n. nasal bone. Both figures are ooe-fouith natural size Marsh, Fifth Arniual Report of the XJ. S. Geological Survey, (figures from the present volume, viz:) figs. 78, 79, p. 276, 1884. The maxillary protuberances of the skull of this specimen ore peculiar for their robust form. They are connected by a well developed transverse ridge. The parietal protuberances are massive, and some\Yhat club-shaped, and present a ridge


. Figure 199.—Maxillary protuberances of Uintatherium segne, Marsh (NTo. 1194); seeu from above. FiGUEE 200.—Tlie same specimen; seen from in front. m'. maxillary protuberance; n. nasal bone. Both figures are ooe-fouith natural size Marsh, Fifth Arniual Report of the XJ. S. Geological Survey, (figures from the present volume, viz:) figs. 78, 79, p. 276, 1884. The maxillary protuberances of the skull of this specimen ore peculiar for their robust form. They are connected by a well developed transverse ridge. The parietal protuberances are massive, and some\Yhat club-shaped, and present a ridge in front, as in Dinoeeras mirabUe and Tiiioeeras h?ffens, evidently formed by the frontal bone rising nearly to the top of the protuberances. The type specimen (number 1194) of this species was collected by Messrs. S. Smith and J. W. Chew, east of Fort Bridger, AVj'oming, in October, 1873. The remains of this species consist of a lower jaw, and other jjarts of the skeleton. The geological horizon of this species is in the Dinoeeras beds of the Middle Eocene. The known remains of this species are preserved in Yale College Museum.
